The wallet built for the quantum age
Claak is a self-custody wallet for Base, Solana, and Bitcoin. Your money is guarded by a post-quantum key that a future quantum computer can't break. This guide shows you everything it can do.
Get started in minutes
Install the extension, set a password, and save your recovery phrase. That's it.
Install Claak
Add the extension to Chrome, Brave, or Edge, then pin it to your toolbar.
Create a new wallet
Pick a strong password. It encrypts your keys on this device only — nothing is sent to a server.
Save your recovery phrase
Write down the 12 words and keep them offline. They are the only way to restore your wallet.
Add some funds
Use Receive to get your address, or grab test coins from the built-in faucet links while on a test network.
Everything Claak can do
A full tour of the wallet, grouped by what you want to get done.
Your wallet
Quantum Vault
Your main account holds your money and is controlled by a post-quantum key, not a normal one.
Execution wallet
A small helper account pays the network fees. You can see it any time, so nothing is hidden.
Multiple accounts
Make as many accounts as you like, name each one, and switch between them in a tap.
Many chains
Switch between Solana, Base, and Bitcoin from one place. Each shows its own balances.
Security levels
Pick Standard for everyday use or Maximum for a larger safety margin on your biggest holdings.
Activity log
See your recent transactions and open each one in a block explorer to check it on-chain.
Move money
Receive
Show your address and a QR code so anyone can send you coins or tokens.
Send
Send ETH, SOL, or USDC. Claak checks the address and shows the value in dollars first.
Multiple tokens
Hold SOL on Solana, plus ETH and USDC on Base. Tap between them to see each balance.
Live prices
Each token shows its current dollar value, so you always know what you're holding.
Confirm before you send
A clear review screen shows who, how much, and on which network before anything leaves your wallet.
Revoke approvals
Cancel any standing token permission you gave an app, so it can no longer touch your funds.
Swap & trade
Instant swap
Trade one token for another in a single step, at the best price across exchanges on Base.
TWAP orders
Split a big trade into smaller pieces over time, from 15 minutes up to 7 days, to get a smoother price.
Open orders
Watch your active TWAP orders fill, and cancel any of them whenever you want.
Wrap & unwrap
Turn ETH into WETH and back, one-to-one, right inside the swap screen.
Slippage control
Set how much price movement you'll accept, so a swap won't fill at a price you didn't expect.
Bitcoin
Bitcoin Vault
A quantum-safe Bitcoin account that hides your key behind a fresh address on every receive.
Fresh receive address
Each time you receive Bitcoin you get a brand new address, which keeps your activity private.
Send Bitcoin
Enter an address and amount to send. Your change returns to a safe, hidden address automatically.
Connect to apps
Connect to dApps
Use Claak with apps on the web through WalletConnect or the standard browser connection.
Choose your mode
For each app, pick your Quantum Vault or a standard wallet, so everything stays compatible.
Sign messages
Approve sign-in requests and typed messages from apps, with the full details shown first.
Approve pop-ups
A small window shows exactly what an app is asking for before you say yes.
Keep your wallet safe
Strong protection by default, plus extra controls when you want them.
Password lock
Your keys are encrypted on this device with your password. No cloud, no account, no server copy.
Biometric unlock
Open your wallet with Touch ID or Windows Hello where your device supports it.
Auto-lock
The wallet locks itself after a short time idle, so a left-open browser stays protected.
Encrypted backup
Save a single encrypted file you can use to restore your wallet in any browser later.
Recovery phrase
A standard 12-word phrase you can reveal any time after confirming your password.
Lock any time
One tap locks the wallet straight away when you step away from your computer.
Account protection (optional)
Allowlist
Only let funds go to addresses you've approved in advance.
Spend limits
Cap how much can leave per transaction and per day, so a slip-up stays small.
Withdrawal timelock
Large or unlisted sends must be announced and wait, giving you time to stop anything wrong.
Recovery owner
Add a trusted backup key that can step in if you ever lose access to your account.
